Java native out of memory errors

As applications grow over time they tend to add features and functions and then one day they run out of native heap as more and more Java classes are piled in. I am promoting this link written by one of my colleages that covers how to use -Xmcrs and setting it to 200M or higher. The fact I have seen this twice in the past month tells me this is a growing (pun intended) problem.

Edit: Oct 30, 2015 and Nov 17, 2015

Native OOM (NOOM) landscape continues to shift. An argument to offset the heap to a different area in the address space is much better (-Xgc:preferredHeapBase). With this new argument, one can place the Java heap allocated past the initial 4g of address space, allowing all native code to use almost all of the lower 4g of space. The Xmcrs option is not used anymore because of this. Xmcrs is still used. Here is the latest technote that supersedes the link I provided previously. More on troubleshooting out of memory errors.
